I don't hate fat people, but I just don't like it.
Fat people are simply not care with themselves and they want to make other people's life harder, even though they can also make other people's life easier (they eat a lot and need few tools to improve their life, so people who sell those things are making money).
I can understand why some men are fat, because men's value are on the money, not the body.
While women, one of their value are on their body, so if the women are fat, it means there's something wrong with them.
Men want to be rich because they know men without money is nothing.
Women know beautifulness is important, but they don't want to chase it? it's the same like men who're not chasing money.
You'd be destroyed by these activists if you said this to their faces. Especially the second part makes no sense.
Have you forgotten that women bear children? If you had to carry additional weight in front of you for 9 months and couldn't work out because it's bad for the baby, you'd get fat too.
Also, some people get fat because of certain condition like diabetes, so don't put all of them in one basket.
To answer the OP's question, I think that there's no black and white here. On one hand fat acceptance promotes being fat, on the other if it makes them feel better it's good, right?
